IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 55,934, dated June 26, 1866.

To all whom it may concern Beitknown that we, W. H. TILLOU and SOLOMON SHUMWAY, of Le Boy, in the county of Genesee and State of New York, have iuvented a new and useful Improvement in Churns, and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side view of a frame with our improvement attached. Fig. 2 isahorizontal section of the same, taken through the line as m, Fig. 1.

Similar letters of reference indicate like parts.

Our invention has for its object to furnish an improved means for imparting a reverse or reci procatin g motion to the churn-dasher, whereby the rapidity and thoroughness of the operation of churning is greatly increased; and it consists in the construction of the gear-wheel, and in its combination with the cog-wheel attached to the upper end of the dasher-handle.

The dasher A consists of two disks or series of rad ial arms, a, attached to the dasher-handle B, and connected by a number of radial arms or bars, (R, the number of which will depend upon the capacity of the churn. The upperend of the handle B works in suitable bearings attached to the upper part of the churn, or to a frame, E, prepared for that purpose, and also to support the gearing for operating the said dasher' handle B.

To the upper end of the handle Bis attached a small horizontal cog-wheel, O, the teeth or cogs of which mesh into the teeth or cogs .of the large cog-wheel D, as shown in Figs. 1 and 2.

D is a vertical cog-wheel attached to the horizontal shaft F. This shaft F revolves in bearings in the frame E, as shown in Figs. 1 and 2.

G' is a crank attached to the end of the shaft F,

done twice during each revolutionof the wheel D. The others, d? and (i are curved in directly opposite directions, as shown in Fig. I, so as to transfer the cogs of the wheel (J to or receive them from the double-curved flanges or cogs (2 without any violentjar in reversing themotion of the said cog-wheel 0.

By reversing the motion of the dasher in this way so often the cream or milk is. kept continuously in violentagitalion, which brings the butter in a very short time, and a greater amount of butter is produced from the cream or milk than can be produced with an ordinary dasher when the said dasher is operated in the ordinary manner.

We claimas new and desire to secure by Letters Patent r The gear or cog wheel D, constructed with curved cogs or [hinges on the side of its rim, substantially as herein described, in combination with the cog-wheel G of thedasher-handle B, for the purpose of frequently reversing the motion of the tlasher A.
